"As a new customer, I was surprised and pleased that the service could be performed on the same day I made the request. Mike was very thorough and professional, and provided a clear explanation of our system and new wi-fi thermostats. Everything was done efficiently - I am looking forward to having Grove maintain our system on our annual maintenance plan."

"GAC services was able to come out for a same day trouble shooting appointment. Jim S arrived on time and was very courteous and professional. He was able to quickly identify the problem with the registers and dampers and able to get warm air flowing to the otherwise very cold areas of the house. In addition, Jim was able to recommend some additional services that would help me achieve the desired evenness of temperature such as an additional return and humidifier for the home. Great experienced master certified technician!"

"I couldn't be happier with the service I received from McCrea Heating and Air Conditioning Services of Maryland. Upon returning from vacation on a 100 degree July day, I found my old HVAC system basically dead (90 degrees in my kitchen!) ... Shane immediately came out to provide an estimate, we signed a contract on the spot, and he kindly provided some freon to hold me over until the new system could be installed. Brian and Nick showed up exactly on time to install the unit, used drop cloths to protect my flooring, and were exceedingly polite and professional throughout. I'd highly recommend this organization."

"Best Air Quality and Restoration did a spectacular job! I can't say enough about the employees. They did an outstanding job! They were punctual,polite and followed social distancing protocols.They assessed the home and cleaned the air ducts quickly and efficiently. I am very pleased with their service and highly recommended this company. I purchased a new home and had them come clean the ducts to improve the homes environment. They showed me before and after pictures and I noticed a difference right away"

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

"Brandon Brock arrived at my home this evening. He is very relatable with a keen sense of professionalism for the services he provide. I now understand how to properly clean my air filter and operate my nest thermostat. I still operate sort of old school but he encouraged me to utilized the nest app to help manage the temperature of my home. Most people use jargons, or acronym when explaining techniques, but Brandon was very patient with me and did not mind explaining anything more than once. It was a pleasure to meet him and started my weekend off in a good way."

Air Conditioning questions, answered by experts

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.
